If it were an ordinary person, under this sudden attack, I am afraid that I would have died on the spot.

The long nails on the claws were as sharp as daggers, which could cut a person's neck in an instant, and these two monsters were obviously familiar with the vital points of the target creature for a long time, and there was no superfluous movement at all.

It's just a pity that they have now encountered the strongest human in the world, and the four of them did not spare bullets, and the bullets chased the two monsters and shot.

And these two monsters are naturally not invulnerable, the bullet enters the body, a terrible scream accompanied by green blood flying, the IQ of the two monsters is quite high, knowing that they are not capable of the enemy, they turn around and are about to crawl away from the top of the hole, but under the cross-fire of the four pistols, they have not had time to escape, they are beaten into a sieve.

Looking at the gray monster that fell from the top of the cave and its body was still twitching, Zhu Yu pursed his lips, sure enough, in this world, there are actually a lot of unsolved mysteries, but they are not known, or not known to the public.

For example, the videos of besieging zombies in some places that have been circulated, such as the videos of aliens that have come out of some places, and ...... Wait a minute.

Ran Jie kicked the two gray-skinned monsters and turned them over.

The eyes are equally gray, with no eyelids, no pupils, and seem to be blind and have no vision.

But think about it, it's normal for something to survive in such a dark environment without vision.

As for why they didn't get out of that crack in the stone, Zhu Yu didn't understand.

It's just that the strange flow of these two monsters is green blood, and the amount is very small, very viscous, and it quickly solidifies in this environment.

Their claws are thin and long, their nails are slightly curved, and they are really sharp, not unlike daggers.

The epidermis has no villi, the blood vessels are not obvious, and the skin elasticity is insufficient, but it is very tough.

Qin Fei took out the military thorn, cut open the monster's stomach, punctured its stomach pouch again, pulled it a few times with the military thorn, and said with a gloomy face:

"They...... I have eaten people. ”

There was a bad smell in the stomach pouch, Zhu Yu didn't squat down to look, but he could also see that this guy did have any chewed pieces of meat in his stomach - human flesh pieces, and some fish meat.

Fish?

The monster has no molars, only sharp teeth, and like a crocodile, it can only bite but not chew - it digests food with a strong stomach function.

Although it looks like a humanoid, it is no longer human.

Or - cavemen?

"Not Croya." Zhu Yu cut the stomach of the other monster with a knife, looked at it and said, "It should be the person who is traveling with her." ”

"Then go ahead?"

"Go on." Qin Fei said while reloading the pistol, "This thing...... It shouldn't exist in the world. ”

Cao Dalong had already loaded the bullets and inserted the military spur in a position that was easy to carry, he nodded, deeply convinced.

The four of them continued to touch forward. Although the previous sound of shooting might have alerted the other members of the opposing party, Zhu Yu and the others still extinguished the flashlight and quietly moved forward.

The environment in the underground passage is extremely complicated, there is no solid cave wall here, instead there are all kinds of large holes and small holes, the cave walls are large and small similar to the appearance of karst caves, at a glance, I don't know the depth, and I don't know if there will be monsters hidden in it.

Fortunately, Zhu Yu's eye of heaven was always open, and he only needed to sweep it to know the movements around him.

So all the way forward, when there was no movement, Zhu Yu did not make a sound.

"Be careful!"

Suddenly, seven or eight monsters in the distance hung from the top of the cave and crawled over quickly, with a clear goal, that is, towards Zhu Yu and them!

"Get ready, there are seven or eight!" Zhu Yu pointed his hand forward, "The ...... who came over scattered"

Although these monsters are hanging upside down, they are very fast, and when Zhu Yu finished speaking, when the pistol pointed forward, they had already appeared in the field of vision!

"Bang bang bang!"

Zhu Yu took the lead in shooting, and the two monsters fell to the ground, but the other monsters rushed over without fear of death!

Ran Jie and the others also shot quickly, several monsters followed one after another, and the last one was a little smaller, I don't know if it was a female or a minor, so I turned around and ran.

But obviously Ran Jie didn't plan to let this guy go, the rapid shooting made it no longer able to grasp the rock on the top of the cave, and when it fell, it was replenished by Qin Fei, and finally landed, twitched a few times, and no longer moved.

Zhu Yu stepped forward and cut open the stomachs of these monsters one by one, there were fish and meat in them, as well as some aquatic plants, which could be seen to be omnivores.

There is no trace of Croya.

Luckily.

"Boss, you said let's take one of this monster's corpses out, can we sell it for some money?"

"Yes. However, it is estimated that we will have endless troubles to deal with later. Zhu Yu waved his hand, "Find someone first." ”

Keep going, go down for a long distance, and I don't see the existence of monsters, I don't know if I was frightened, or if it was less in itself?

Zhu Yu and the others reloaded as they went, ensuring that the pistols could be fully loaded at any time.

After all, if a group of people gush out, there will be no bullets at that critical time, won't you be blind?

Eventually, they came to an empty underground space, like a hall, with a lot of dried slime and blood on the ground.

Some sharp stone chips were scattered on the ground one by one, and there were some uneaten bones, fish bones, and some rhizomes of marine plants on the ground.

"Is this already close to the sea?" Cao Dalong asked softly, "Where did those fish bones come from?" ”

Zhu Yu glanced around, but still found no trace of Kroya's breath, and he was a little relieved.

The hall is surrounded by more than a dozen large and small openings that lead in unknown directions. Zhu Yu and the others came down from one of the holes, and Zhu Yu guessed that this should be the place where those monsters ate and gathered.

They should also have places to rest and hide.

The eye of heaven swept over those holes, and soon Zhu Yu identified a hole with a large amount of fresh breath, and he pointed with his hand:

"Go there!"

Ran Jie and the others followed without saying a word.

Passing through the small hole, the space passage inside gradually became larger, but it was still the kind of irregular trapezoidal shape that was large at the top and small at the bottom, Zhu Yu guessed that these monsters should like to hang and crawl on the top of the cave all year round, so it became like this.

Before he could go far, a monster came out of the small hole next to the cave in front of him, and just as he was about to escape, he was killed by Ran Jie.

Next, from time to time, there are lonely monsters, or fleeing, or attacking, but they do not escape the fate of being hunted down.

This is the third time that Zhu Yu has reloaded the three of them.

Fortunately, the space is large enough, even if it lasts for ten years, Zhu Yu's bullets are enough.

It's a big deal to change guns.

Eventually, they came to an underground lake – or subterranean sea – that connected to the Atlantic Ocean outside.

There are more than a dozen monsters catching and collecting fish, kelp, and other plants on the beach.

Zhu Yu's arrival made these monsters panic, some of them rushed into the sea, and some of them quickly ran to the nearest cave.

More of them let out ugly strange screams and rushed towards Zhu Yu and them!

"Bang bang bang!"

Accompanied by those strange screams, they were greeted not only by bullets, but also by military spurs.

Because the number of monsters is a bit large, the pistol can't be completely solved before the other party rushes over, and the last three monsters were stabbed to death by Zhu Yu, Ran Jie and Cao Dalong.

Several men took thorns and cut open the stomachs of these monsters, and found that there were no human flesh in them.

"They're probably not at the level of eating human flesh yet." Cao Dalong guessed.

"No matter what, none of these guys can be spared." Ran Jie gritted his teeth and said.

He was almost bitten by one of the monsters just now, and looking at the sharp teeth, Ran Jie felt that he needed to live a bittersweet life again.

How long has it been since you were injured?

Isn't it a bit too pampered by now?

They hunt down monsters, big and small. These monsters seemed to have known that they were not Zhu Yu's opponents, and they fled quickly one by one.

However, no matter where they fled, Zhu Yu's Heavenly Eye could find it. The number of monsters has decreased one by one, and until now, Zhu Yu has not found Croya's breath.

This is indeed good news.

In the end, Zhu Yu and the others killed all the monsters they could see. The underground cavern became dead silent.

"It shouldn't be......" Cao Dalong frowned, "We should have searched the entire underground cave, and there was no trace of Kroya......

He didn't finish his words, but his expression was not difficult to guess, and he felt that Croya was more than lucky.

"Look for it again." Ran Jie pursed his lips and said.

Zhu Yu closed his eyes and began to review this action.

It starts with entering that underground hall and ends with the final return to the underground hall.

He opened his eyes and looked carefully at the entrances on the wall again.

All the traces have been searched, and not a single one has been spared.

Suddenly, Zhu Yu raised his head.

He found that at the top of the cave, there was a small hole that barely allowed a person to drill through.

It was very dry around the opening, and it didn't look like a monster had ever been there.

However, Zhu Yu knew that he couldn't let go of even one possibility.

"Come, help me up!" Zhu Yu pointed to it.

Three meters high, Ran Jie and Qin Fei bent their knees in two lunges, holding up with both hands, and when Zhu Yu jumped up, the two of them just supported Zhu Yu's left and right feet, and then slammed up!

Zhu Yu rose in the air, reached out to reach the entrance of the cave, and then grabbed the protruding rock on the wall of the cave and drilled in.

The entrance to the cave was less than a meter upwards, and then it turned to the right.

Zhu Yu drilled into the hole, and after making sure that there was no danger, he threw down a rope.

He pulled the rope and pulled Ran Jie up, and then Ran Jie took his place.

Unlike other caves, this passage is always narrow and can only be climbed.

More than thirty meters later, the end of the passage was blocked by several stones.

These stones are stuck very hard, if it weren't for Zhu Yu's great strength, he really couldn't move the stones.

Removing the stones, revealing what was left of the cave—a wave of heat rushed over with a red glow.

And moisture.

Zhu Yu jumped down.

To his surprise, there was a field of lava below, and a small amount of seawater exposed at the edge of the stone.

There are only a few dozen square meters where it can stand.

And in this dozens of square meters, there are two monsters, holding a fish, close to the lava, "roasting"!

Seeing Zhu Yu and them jump down, the two monsters were startled, and the fish in their hands fell off into the lava, and soon turned into a ball of flames.

The two monsters kept backing until they were almost at lava.

Zhu Yu found that these two monsters were smaller than the ones outside, and the eyes of heaven could see that they were even more aging.

This is......

Incarceration, or punishment?

Although it seemed that these two monsters were not capable of killing humans at all, Cao Dalong was able to finish them off with the first few shots.

He went over and dragged the monsters over and slipped open their bellies.

"Good guy, you still eat the same kind!" Cao Dalong looked at the contents of the monster's stomach and said in surprise.

Zhu Yu looked left and right, and could obviously see some flashes of light from the magma.

But none of that matters right now. He turned his head and said:

"Let's go, the fork in the road before we entered the cave, it is estimated that we will have to find clues from there to find Croya!"

Ran Jie, Qin Fei, and Cao Dalong all knew that this matter could not be delayed, and they all quickly drilled into the stone cave and crawled towards the hall.

They returned the way they came, drilled through the cracks in the rocks, and returned to the second fork.

"Grab a bite to eat while walking." Zhu Yu said, "Replenish your energy." Don't worry, I'll ......"

"Boss, I'd better come!" Qin Fei stepped forward, "You're in the middle." ”

"I'll come, I'll come, this order can't be messed up!" Ran Jie took out a piece of compressed dry food, and while chewing, he rushed into the hole on the right, "Let's not grab it!" ”

The four of them groped their way forward while eating, and soon, they made new discoveries.

Here, blood was spilled on the ground.

Someone was dismembered, some pieces of clothing, and parts of field equipment.

Ran Jie and the others looked at Zhu Yu.

"Not Croya." Zhu Yu shook his head, "A middle-aged woman, white. ”

A few people continued in silence - the danger in the wild is really everywhere. Especially this kind of place that has not been explored much in itself.

In the dark, there were some strange sounds in the cave in front of him, Zhu Yu's heavenly eye was always open, and he found that more than twenty meters in front of him, three monsters were hanging upside down on the roof of the cave, communicating with each other.

The three monsters didn't rush over, and they looked a little strange.

As Zhu Yu and the others advanced quickly, the three monsters actually retreated, and soon disappeared into the long crypt.

The crypt continued to descend, circling, and the direction kept changing, and Zhu Yu guessed that they had gone deep into the ground.

Finally, they came to an underground space.

It's the end of it. The underground space is not large, the size of a basketball court, but it is very high, and the top of the cave is more than 20 meters above the ground.

Zhu Yu looked up and saw a hole more than a person high looming more than ten meters from the ground.

If it weren't for the eye of the sky, even if the flashlight was turned on, it would be difficult to find the hole in this situation.

There was a faint mark of blood near the entrance of the cave, the kind that had been smeared.

"They should be in there." Zhu Yu pointed to it.

"I'll climb up!" Qin Fei acted immediately.

"I'll do it." Zhu Yu's movements were much faster than him, with the help of the protrusions on the rock wall that were not obvious, Zhu Yu easily climbed up like a gecko, and a minute later, he came to the entrance of the cave, and then hung down the rope and hung Ran Jie and them up.

The entrance to the cave is not deep, but only four or five meters. The four of them walked out of the passageway, and outside was a huge space like an underground city.

Occasionally, there are stone pillars supporting the top and bottom like load-bearing columns, but the large and large spaces connected to each other give Zhu Yu the illusion of entering the city in the center of the earth.

That strange voice sounded again, and Zhu Yu looked in the direction of the sound.

At the top of the cave more than thirty meters away from them, seven monsters were hanging upside down looking at them - these monsters had traces of blood on the corners of their mouths, and their gray-white eyes looked at Zhu Yu's gaze, as if they were looking at delicious food.

Greedy.

It's just that there is caution. They didn't pounce.

Zhu Yu walked over without hesitation, and took out a strong flashlight as he walked—the kind that flashed a large piece.

"In that direction, there are seven monsters, I'll shine on them, and if you see them, you will start fighting!"

Zhu Yu took a few steps forward and found that there was a monster that seemed to be scared and was about to escape, so he immediately turned on the flashlight!

The whole underground space suddenly felt like daylight!

The screams rang out!

Those monsters, you can't see the bright light!

Just when they were covering their eyes with their hands, Ran Jie and the others had already seen the target clearly, and they shot "bang bang bang"!

At the moment of life and death, no one left their hands.

Although the vitality of these monsters seems to be much stronger than that of ordinary people, under the "care" of four pistols and dozens of bullets, they finally fell down one by one, twitched on the ground, and finally stopped moving.

The sound of gunfire echoed in the underground space, and the smoke slowly dissipated, Zhu Yu and the others did not get close to those monsters, and changed the magazines alternately in pairs.

The overturning of the boat in the gutter is often encountered, and no one dares to be careless.

After changing the bullets, Cao Dalong stepped forward and cut open the stomachs of these monsters.

"I've eaten human flesh."

"Not Croya." Zhu Yu confirmed again.

Cao Dalong also breathed a sigh of relief. He didn't want the stinking and blurry flesh he pulled out of the monster's belly to belong to Croya's lovely princess.

"Let's move on."

The underground space is quite large, but with the blessing of Tianyan, Zhu Yu can still see that this underground space is slightly rectangular, and what they are facing is the direction of the long.

The border can be roughly seen on the left and right, I don't know if it's because of the gunshot, or because of the monster's screams before dying, they have been walking out for nearly a hundred meters, and they haven't seen the existence of other monsters.

Until the end of this underground space, Zhu Yu suddenly found something scattered on the ground.

He was startled and stopped.

"Boss, what's wrong?" Ran Jie realized that something was wrong and asked.

"Front...... Clothes. Zhu Yu pointed ahead, and on the edge of a pillar, there were some fragments of clothes.

"Croya's clothes?" Qin Fei was the calmest at the moment, and he immediately asked:

"I'll go take a look!"

Pulling out his flashlight, Qin Fei found those fragments of clothes.

It was indeed worn by women, but there did not appear to be any blood on it.

"This clothes ......" Qin Fei turned his head to look at Zhu Yu, "Boss, it's torn, but there is no blood." ”

However, in Zhu Yu's heavenly eyes, there were faint traces of blood near the clothes.

Croya's!
